Hello. I'm fresh meat! This is my first post, so if there are widely discussed answers for these questions, sorry I posted this. I couldn't think of the proper criteria for a search.

Okay, if I have Limewire open, I cannot play video in any external player. The audio plays but the video just doesn't show up.

Also, when I play games like Stepmania or Blockland with Limewire open, the screen doubles and offsets. This is hard to put into words so please refer to the attatchment.

I have an nVidia video card and Ace Megas Codecs Pack (Meaning I have alot of flipping codecs.) But I doubt it's my codecs causing this problem.

This is a large and rather inconvenient problem so any help is greatly appreciated, thanks.
